Sepioloidea lineolata reproduce sexually. In order to mate, a male striped pyjama squid will grasp a female striped pyjama squid and place her to where they are both head-to-head. The male squid then inserts a spermatophore, or a sperm packet, near where the female will store the sperm until she is ready to lay eggs.
In addition to camouflage and appearing larger in the face of a threat, squids use color, patterns, and flashing to communicate with one another in various courtship rituals. Caribbean reef squid can send one message via color patterns to a squid on their right, while they send another message to a squid on their left. [9] [10]
Squid are also known to be sensitive to temperature, salinity, and circulation in the water. [10] These habitat components can affect reproduction and life cycles. Chinese spear squid at different growth stages sometimes have different names among fishermen: they call the larvae of squid "small rolls", and the sub-adults are called "middle ...

Most squid species whose reproduction has been observed have been seen to deposit eggs on the sea floor, then leave the eggs to hatch on their own. Five female Gonatus onyx squids have been observed in Monterey Canyon dragging a membrane sack containing 2,000 to 3,000 developing eggs. [ 5 ]
Video of swimming bigfin reef squids. Bigfin reef squids exhibit two most common social body patterning and posturing behaviours related to mating. [28] The first is dubbed "accentuated gonads", in which they will sometimes increase the visibility of their gonads while reducing the rest of their body colouration. This makes their reproductive ...
Gonatus onyx is in the class Cephalopoda and in the phylum Mollusca.It is also known as the clawed arm hook squid or the black-eyed squid.It got these names from the characteristic black eye and from its two arms with clawed hooks on the end that extend a bit further than the other arms.
However, spawning occurs throughout the year for this species. The squids reproduce sexually; they have a mating ritual that can be behavioral, physical, and morphological. During this process, the male hold the female and insert their hectocotylus into the females' mantle cavity: this is also where the fertilization of the egg occurs.
